An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.
A new study led by clinician-researchers at Beth Israel Deaconess Medical Center testing the safety and effectiveness of anticoagulant strategies for patients with atrial fibrillation who undergo stenting procedures has shown that therapies combining the anticoagulant drug rivaroxaban with either single or dual anti-platelet therapy were more effective in preventing bleeding complications than the current standard of care.
Congenital heart disease (CHD), a group of abnormalities in the heart that develop before birth - including holes in the heart, leaky or narrow valves, and incomplete or missing parts - affects nearly one percent of all babies born in the United States each year - upwards of 40,000 infants.
Atrial fibrillation patients with a prior history of stroke who undergo catheter ablation to treat the abnormal heart rhythm lower their long-term risk of a recurrent stroke by 50 percent, according to new research from the Intermountain Medical Center Heart Institute.
EuroEcho-Imaging 2016 brings advanced techniques to the bedside with international experts set to discuss the use of holograms and 3D printing to guide interventions.
Combination therapy utilizing two approved immunotherapy drugs for cancer treatment may cause rare and sometimes fatal cardiac side effects linked to an unexpected immune response.
Scandinavian cardiovascular diagnostics specialist CardiNor AS today announced two new studies have been published by the group at Akershus University Hospital led by Professor Torbjørn Omland and Associate Professor Helge Røsjø in leading journals that strongly support secretoneurin as a new, important biomarker for cardiovascular disease.
Duke University biomedical engineers have harvested genes for ion channels from bacteria that, with a few tweaks, can create and enhance electrical signaling in human cells, making the cells more electrically excitable.
Affecting 33.5 million patients worldwide, atrial fibrillation is the most common form of cardiac arrhythmia. As if having an irregular heart beat wasn't troubling enough, patients with atrial fibrillation are also much more likely to have a stroke.
A new, computer-based screening method could reveal the virus-fighting potential of drugs originally developed to treat other conditions, reports a study in PLOS Computational Biology.
The heart cannot regenerate muscle tissue after a heart attack has killed part of the muscle wall, and that dead tissue can strain surrounding muscle, leading to a lethal heart enlargement.
The promise of stem cells to treat cardiovascular disease may soon be a step closer to clinical application as scientists from three institutions seek to perfect and test three-dimensional "heart patches" in a large animal model — the last big hurdle before trials in human patients.
VTT Technical Research Centre of Finland has developed a mobile app and thumb-size device that help to prevent cerebral infarctions at an early stage, during asymptomatic atrial fibrillation.
Medications prescribed to prevent heart attacks such as statins and aspirin are also associated with reduced heart attack severity, according to research published in PLOS ONE.
Two PhD students, who secured sponsorship from leading medical device designer and manufacturer ITL, have revealed progress on the development of ground-breaking medical devices.
The Canadian Journal of Cardiology has just released the 2016 Focused Update to the Canadian Cardiovascular Society's atrial fibrillation (AF) guidelines.
In the August 31 issue of Science Translational Medicine, new research from the University of Chicago shows how deficits in a specific pathway of genes can lead to the development of atrial fibrillation, a common irregular heartbeat, which poses a significant health risk.
For heart failure patients with cardiac implantable electronic devices (CIEDs), remote monitoring of their condition does not improve outcomes compared to usual care, according to Hot Line results presented at ESC Congress 2016 and to be simultaneously published in JAMA.
The risk of traffic accidents is increased by 50% in patients with an implantable cardioverter defibrillator (ICD) compared to age and gender matched controls, according to a Danish nationwide registry study presented at ESC Congress 2016 today.
Alcohol related hospitalisation is associated with a doubled risk of ischaemic stroke risk in patients with non-valvular atrial fibrillation, according to a study presented at ESC Congress 2016 today by Dr Faris Al-Khalili, cardiologist, Karolinska Institutet, Danderyd Hospital, Stockholm, Sweden.
Direct catheter-based thrombectomy is equally effective to bridging thrombolysis in the treatment of acute ischaemic stroke, according to results from the observational PRAGUE-16 registry study presented at ESC Congress 2016 today.
